Scientists from MIT and the University of California have figured out a way to engineer plants to glow in the dark. This isn’t the first time but it is the first time that it has been on whole plants without initially do some tricky genetics. They use nanoparticles that introduce the same components that fireflies use to glow in the dark. These tiny particles are forced into plant cells by pressure and once there they make the plants glow. There are lots of applications but we kind of like the idea of being able to mow in the dark. OK, that is a joke.
